(Originally posted as a reply to a dead comment) While there was some controversy regarding how COVID spreads in the early days (droplets vs aerosol, how many virions you needed to be exposed to to become infected, whether asymptomatic transmission was possible, etc.), most of the details were fairly well understood within a year after the pandemic started. Plus, we were already aware that coronaviruses are capable o…
1. Mass movement of classrooms/education to the outdoors in climates where this was possible, despite the outdoors being an excellent way to reduce exposure to an airborne pathogen.
2. Mass campaigns to deploy air purification devices/filtration and modernize existing HVAC. Air quality is often garbage anyway indoors because of bad hygiene from people and natural pollutants. Slapping an air filter to a box fan is an extremely cheap and effective (if loud) solution!!!! We had no excuses for not having government money spent here. It'd also make these stupid wildfires much easier for most to deal with, and as a bonus reduce every respitory related negative externality there is.
3. Educating people that something as simple as cracking/opening your windows while driving is effective at circulating air such that you can massively reduce your chance of transmitting COVID.
But what did we get instead? Masking mandates - leading to a massive amount of physical pollution in landfills, political radicalization against left-wing movements, a whole lot of annoyed glasses wearers, etc. Lots of cloth masks which ultimately worked poorly and lead to economic boom-bust cycles in a core medical commodity in an already fucked supply chain. Lots of fake N-95s, leading to worse QC across the industry which still plagues it today.
We also got insane "6 feet" requirements that did nothing to rescue people from extremely poorly ventilated/purified environments which made mass spread of the virus in places like schools inevitable.
I will never forgive the public for how stupid they are when it comes to anything involving air quality. We have learned basically nothing except about mRNA (which is awesome) and about how much we hated democracy from the stupid boomer flu.
P.S: Bonus, the fact that Americans don't wash their assholes after using the bathroom (no bidet culture like in Asia) means that we unironically are spreading it all anyway by being around others indoors:

America should have had a mass campaign to put bidets on every toilet nation wide in the 50s. Let's do it now.
